Newbie weed smoker HELP

I tried smoking weed for the second time this past week. I have horrible anxiety and just wanted to freaking relax for once. I tried weed for the first time back in June of this year but was drunk and don't really remember the effect. I do remember laughing and eating a whole Costco pizza. LOL.

All I know is as soon as I smoked this time my face felt heavy and my body went numb. I felt like I was outside of myself and started to panic. I kept forgetting what I was saying and started feeling like I forgot how to swallow and breathe and that my mouth was too small. I also heard an ice cream truck playing some sort of song over and over in my right ear. 😩. I know from the last time it didn't have this effect so it wasn't laced with something else. It is from the same batch. I only took one puff and it knocked me on my ass. What do you guys think? I would like to try again but if it means of feel like THAT again no way. I just want to finally be able to live in my own body without my heart and thoughts racing. In need of advice badly.
